Is there catnip growing nearby?

I used to get the same thing; the squash plants would be healthy until
they started blooming, then they would get this virus -- yellow squash
would be green and warty, zucchini would turn a sick yellow. The plants
would get this twisted tortured look to them and die.

My brother mentioned the catnip to me. He says it's an alternate host
to a squash virus. I figure the squash and catnip are blooming at the
same time and bees visit both and carry infected pollen to the squash.
The virus infects the fruit and then moves it's way down.

I started a catnip eradication campaign, and I didn't grow any squash
for a couple of years until I got the catnip under control. And the
problem went away. Might be a coincidence, I dunno.

Catnip still comes up wild around here, but I pull most of it up (and
feed it to the cat) and I never let any of it bloom.

Hope this helps, :-)

Nope, no catnip, just dill, basil, chives and tarragon.
